Ingredients Needed to Make Low Carb Lasagna Soup
- 2 tablespoons garlic-infused olive oil
- 3.5 ounces raw cubed pancetta
- 1/2 cup leek, dark green parts only, finely chopped
- 1 pound ground beef
- 2 tablespoons tomato paste
- 1 cup water
- 2 cups low sodium beef broth
- 28 ounce can fire roasted crushed tomatoes
- 3 tablespoons Italian seasoning
- 2 teaspoons salt
- 1 teaspoon ground black pepper
- 12 ounce package hearts of palm lasagna sheets, drained, rinsed, patted dry, and chopped into thirds
- 1/4 cup heavy cream (optional)
- 1 cup mozzarella cheese, finely shredded
- 1/2 cup parmesan cheese, finely shredded
- Fresh Italian parsley, finely chopped, for garnish
Instructions to Make Low Carb Lasagna Soup – Step by Step
Step 1: Start by prepping your hearts of palm lasagna sheets. Pour them into a fine mesh strainer, rinse thoroughly with cold water, and pat them dry with paper towels. Once they are dry, carefully chop them into thirds so they are easy to eat on a spoon. Setting these aside now keeps your workspace tidy once the heat is on.
Step 2: If using an Instant Pot, hit the Sauté button. When the screen says Hot, add your garlic-infused oil and the pancetta. Let the pancetta brown and crisp up for about five minutes. Remove the meat with a slotted spoon, keeping the savory juices in the pot, and add your leeks, cooking them until they soften up and become aromatic.
Step 3: Add the ground beef to the pot, breaking it up with a spatula as it browns. Once the beef is cooked through, stir in the tomato paste for a minute to deepen the flavor. Hit Cancel on the pot, pour in the water, and scrape those delicious brown bits off the bottom—that is where the real flavor hides!
Step 4: Now, stir in your broth, crushed tomatoes, Italian seasoning, salt, pepper, the hearts of palm sheets, and the reserved pancetta. Secure the lid, make sure the valve is set to sealing, and cook on manual high pressure for 20 minutes. A quick manual release of the pressure afterwards, and you are ready to finish the dish.
Step 5: If you want an extra touch of richness, stir in the heavy cream once the soup has cooled for a moment. Serve it in deep bowls topped with a generous amount of the mozzarella and parmesan blend. Sprinkle a little fresh parsley on top to bring it all together.
Chef’s Tips for a Perfect Result
- Always rinse and dry your hearts of palm sheets thoroughly to ensure the best texture.
- Use a quality spatula to break up the beef, as even pieces make for a much better spoonful.
- Let the soup sit for a few minutes after opening the lid; this allows the flavors to meld and the heat to settle.
- Toss your cheeses together in a small bowl before topping the soup so you get a perfect mix of melt and flavor in every bite.
Variations and Substitutions
- Vegan Option: Swap the beef for crumbled tempeh or extra firm tofu, and use coconut cream instead of dairy cream.
- Gluten-Free Alternative: This recipe is naturally gluten-free as long as you confirm your beef broth and seasonings are certified GF.
- Budget Swap: If pancetta is hard to find or out of budget, use a little extra ground beef or some finely chopped, high-quality turkey bacon.
How to Serve and Pair
Serve this soup in deep, warm bowls to keep the cheese melty. It pairs beautifully with a simple side of roasted asparagus or a fresh, crisp green salad tossed with a light vinaigrette. If you have guests, a little sprinkle of red pepper flakes adds a nice pop of heat.
Storage and Reheating
Refrigerator: Store leftovers in an airtight container for up to four days. The flavors often improve by the next day as the hearts of palm soak up the broth.
Freezer: You can freeze this soup for up to two months, though the texture of the hearts of palm may soften slightly upon thawing.
Reheating: Reheat gently on the stovetop over low heat, stirring occasionally to ensure the cream does not separate. Avoid boiling it rapidly.
